近30年国内外食物系统研究的热点与趋势

Hot Spots and Trends of Food System Research in the Past 30 Years

自古以来食物问题就是关系到民生国计的重大问题,目前全球食物系统面临诸多挑战,随着全球化的深化以及新冠肺炎疫情的蔓延,农业劳动力流失、消费需求转型、耕地资源减退等一系列问题加速了学界对食物系统的关注。为了解国内外食物系统研究发展的现状和趋势,文章基于中国知网全文数据库(CNKI)和Web of Science (WoS)数据库,采用可视化图谱对比分析法,利用CiteSpace科学文献可视化分析软件,对1990~2022年间国内外各年度文献的发表量、研究单位、时区和关键词展开可视化分析。结果表明:目前国外食物系统研究已初具规模,相关研究文献在数量上整体呈现上升趋势,研究单位网络密度大,交流多且合作紧密。同时,国内研究进入刚起步阶段,发文量少、机构间尚未形成良好的合作机制;通过对关键词图谱分析得出,后疫情时代的食物系统韧性研究属研究热点,食物系统的转型成为研究趋势。最后,建议国内高校、研究机构等不仅要加强合作交流,形成较为成熟的研究团队,还要加快学科交叉融合以及与企业相互之间的深度融合,推动国内食物系统的快速转型和高速发展。

Since the ancient times the food problem is related to people’s livelihood countries of major is-sues, the global food system faces many challenges, with the deepening of globalization and the spread of the new champions league pneumonia outbreak, the agricultural labor force, the transformation of consumer demand, cultivated land loss, loss of a series of problems such as accelerating the attention of the academic circles on the food system. In order to understand the current situation and trend of food system research and development at home and abroad, based on CNKI and Web of Science (WoS) databases, this paper adopted visual map comparison analysis method and CiteSpace scientific literature visualization analysis software. The publication volume, research unit, time zone and keywords of domestic and foreign literature in each year from 1990 to 2022 were analyzed visually. The results show that: At present, foreign food system research has begun to take shape, and the number of relevant research documents shows an overall upward trend. The research units have a large network density, more exchanges and close cooperation. At the same time, domestic research has just entered the initial stage, with few publications and no good cooperation mechanism between institutions. Through the analysis of keywords, it is concluded that the resilience of food system in the post-epidemic era is a research hotspot, and the transformation of food system has become a research trend. Finally, it is suggested that domestic universities and research institutions should not only strengthen cooperation and exchange, form a relatively mature research team, but also accelerate the interdisciplinary integration and deep integration with enterprises, so as to promote the rapid transformation and rapid development of domestic food system.
